SPECIFICATION forming part of Letters Patent No. 646,849, dated April s, 1900.

Applicationled May 10, 1899.

To all whom it may concern:

Be it known that I, PHILIP' LrNDEMEYR, a resident of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Tools for Foi-mi ng the N ecks of Bottles and other Vessels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

The invention relates to tools for molding and forming the necks of bottles and the like; and it has for its object to provide simple and efficient means for closing a sectional mold and locking the sections when closed, which means also permits the convenient substitution of various mold-sections when desired.

The invention consists in the construction hereinafter described and pointed out.

In the accompanying drawings, Figure 1 is a side elevation of the improved tool, the mold-sections being open and each shown in section. Fig. 2 is a partial section showing the mold closed, the view being at right angles to that of Fig. 1. Figs. 3 and 4 are perspectives of the mold-sections. Fig. 5 is a partial perspective of the tool. Fig. 6 is a partial section at right angles to that shown in Fig. 2, the mold sections being closed. Figs. 7, 8, and 9 are perspectives of ball-housing, mold-inclosing cylinder, and opener, respectively.

Numeral l is a bow comprising two members joined by a spring 2.

3 denotes a stem connected to the bow by nuts 4, as indicated.

5 is a hollow stem extension upon which is rotatably supported a housing for series of antifriction-balls 7.

A ball-housing is constructed as follows:

5 denotesa ball-seat, shown in the present instance as asleeve on the stem extension 5. It is provided with a removable ring 5, and these parts, in cooperation with an exterior ring 8, sloped substantially as represented, house the balls 7, which obviate friction between the rotating mold and said sleeve. The housing-ring 8 is slotted at 9 to receive moldsection stems 10, which are supported by pivots 11, fixed in the walls of the slots. At the Serial No, 716,207. (No model.)

stops the inward movement of the outer end of the stems.

13 are shoulders formed on the stems and adapted to engage the bridges 12 when the stems and mold-sections are thrown outwardly. The entire ballbearing housing, With the housed balls, is removable. The mold-section stems are separable from the housing andthe sections are separable from the stems. By this construction mold-sections and their stems are made separately removable and provision is made for substituting molds of different form.

The mold-sections are denoted b v 14, and 15 are screws for connecting them with their stems. For certain purposes of this invention and its description each mold-section and its stem, instead of being considered as separate elements, may be one and the same element, and particularly in respect to the operation of the bandv or ring 27, which cooperates with the mold-sections through the l medium of the stems. Obviously also this cooperation is independent of the detachability of the mold-sections. The latter feature is deemed important in many cases, for the reason that it provides for the substitutionv of fresh molds whether of the same or different design. Said sections each comprise parts 19 and 19', which together constitute the mold-bottom and cooperate to form the bottle-mouth and a shoulder on the bottle-neck near the bottle-mouth.

A shoulder 18, having a surface approximately continuous with the adjacent bottom part 19 of the mold, is provided on the part 6 ofthe opener, which part is fixed to the stem extension 5.

16 denotes a neck-opener fixed to the stem extension 5 and slotted to receive expanderfingers 17. The expander-ngers are recessed at 2O to permit the shoulder 19 to rotate therein when the expanding and finishing fingers are open and operative. They have extensions 17', whereby they are opened and closed. The opener 16 and the expanding-fingers 17 are supported through the medium of the stem extension 5, to which they are detachably connected. These parts are separable together from the tool, and they are also separable fromV each other. In practice the com- IOO bined opener, expander', and stem extension may be kept in stock and fresh ones substituted for those having openers injured by repeated ycontacts with hot metal or otherwise or whenever it is desired to renew the parts for any. reason. It is also practicable to renew either of the single parts of this combination in like manner.

The mold-sections and their pivoted stems, as well as the ring 8 of the ball-bearing housing, rotate freely about the stem extension 5, opener 16, and expander 17.

21 denotes a cylinder rotatably mounted contiguous a ring 22, which has horns 23 operatively connected with the bow by means of the holes 24, whereby the compression and expansion of the bow move said ring and the cylinder 2l. lengthwise the tool.

A second ball-housin g is constructed as follows:

25 is a sleeve on the stem extension and movable lengthwise thereof, which sleeve, in coperation with the ring 22, screwed thereon, and with the ring 25', houses the balls 25. These balls and their housing, consisting of said rings and sleeve and cylinder 21, which is rigidly secured to the ring 25', move lengthwise on the sleeve extension 5. The cylinder 2l is slotted at 26, adjacent the slots 9 of the ring 8, and the stems lO play in said slots 9 and 26.

27 denotes a band or ring fixed to the cylinder and bearing on stems l0. These are provided with inclined faces 28 and 29 on opposite sides of the stem pivots or fulcrums 11 and in such relation to the cylinder and its band that when the cylinderis moved forward and its band carried over the inclines 28 the mold-sections are closed, and when the cylinder and band are oppositely moved the band passes onto the inclines 20 and opens the mold.

The cylinder2l has an inside circumference as large as the proximate exterior part of the mold, and when advanced to close the moldsections it embraces them, as indicated in Figs. 5 and 6, and at such time locks and holds the sections together firmly and independently of the bearing of the band 27 on the mold-section stems.

The moldsections are guided to proper alinement in their closed situation by lugs 14 on one section entering recesses 14C on the other, the parts having inclined faces which fit and guide each other when brought together by the closing of the mold, as shown.

Having thus described my invention, what I claim isl. In a tool for forming the necks of bottles and the like, a bow, a stem, a sectional mold, a ball-bearing housing rotatable about the stem and comprising an exterior ring, and mold-section-supporting stems pivotally supported in said ring.
